World War II
Upon the outbreak of World War II, Gilormini offered his services to the Royal Air Force and served with them. As a member of the RAF, he flew in a squadron of P-39s from England to North Africa and participated in the Allied invasion of Oran. He served with the RAF until November 30, 1942, when he joined the United States ArmyAir Forces with the rank of second lieutenant. In October 1942, he was assigned to the 346th Fighter Squadron and flew the P-39 interceptor. In March 1943, he was transferred to the 345th Fighter Squadron of the 350th Fighter Group in North Africa and Italy, to replace pilot losses. He stayed with the 345th "Devil Hawks" and flew a P-47 Thunderbolt until February 1945. On one occasion Gilormini led a squadron in an attack against Nazi positions in Conneto, Italy. During the attack his P-47 was struck by enemy anti-aircraft fire. Gilormini made a nose dive which put out the flames consuming his aircraft and rejoined his squadron. His squadron destroyed a strategic railroad and vehicles which were transporting military equipment. During the war he was promoted to captain and flew a total of 200 combat missions over England, North Africa, Corsica and Italy. On May 19, 1943, Gilormini was involved in an aircraft accident when his P-39 went down over Maison Blanche, Algiers. In an interview, Colonel Earl Miller, a former buddy and roommate of Gilormini, recalled the following: In 1945, Gilormini was awarded the Silver Star, G.O. #27, for "Conspicuous Gallantry in Action" for his actions during the Conneto, Italy mission, while assigned to HQ, 12th Air Force. Gilormini and Miller flew their last flight in Italy together giving air cover for General George C. Marshall's visit to their group at Pisa. They both returned to the United States on the same ship. Gilormini was also the recipient of five Distinguished Flying Crosses. The Distinguished Flying Cross is a medal awarded to any officer or enlisted member of the United States armed forces who distinguishes himself or herself in combat in support of operations by "heroism" or extraordinary achievement while participating in an aerial flight. Also, in 1945, Puerto Rican poet Francisco Rojas Tollinchi paid homage to Gilormini in his poem "Recuerdo yaucano".
